Questions about the long-term evolution of inequality, the concentration of wealth, and the prospects for economic growth lie at the heart of political economy. But satisfactory answers have been hard to find for lack of adequate data and clear guiding theories. In Capital in the Twenty-First Century, Thomas Piketty analyzes a unique collection of data from twenty countries, ranging as far back as the eighteenth century, to uncover key economic and social patterns. His findings will transform debate and set the agenda for the next generation of thought about wealth and inequality.Piketty shows that modern economic growth and the diffusion of knowledge have allowed us to avoid inequalities on the apocalyptic scale predicted by Karl Marx. But we have not modified the deep structures of capital and inequality as much as we thought in the optimistic decades following World War II. The main driver of inequality—the tendency of returns on capital to exceed the rate of economic growth—today threatens to generate extreme inequalities that stir discontent and undermine democratic values. But economic trends are not acts of God. Political action has curbed dangerous inequalities in the past, Piketty says, and may do so again.A work of extraordinary ambition, originality, and rigor, Capital in the Twenty-First Century reorients our understanding of economic history and confronts us with sobering lessons for today.

Artificial intelligence promises to transform diagnosis of heart disease

Rollout of stethoscope with pioneering technology could save lives and ease the strain on the NHS

The goal of the AI stethoscope, designed by Mayo Clinic spin-off Eko, is to close these gaps and save the lives of heart patients who end up needing emergency care in hospital. “This is a route to treating patients early while they wait,” said Kelshiker.

DSO

(1)期间平均法
DSO=期未应收账款余额/这一时期的销售额×这一时期的天数
(2)倒推法
就当前客户应收账款余额,按此余额形成日开始往前推算,以以前各月的实际回款规模,收回当前应收账款余额需要多少天,这个总天数即为DSO。
(3)账龄分类法
这种方法综合考虑了赊销和账龄的关系,对一段时期内不同账龄的应收账款计算DSO,最后相加得出总赊销额的DSO,账龄分类法可对每笔应收账款一目了然,并通过计算每个阶段应收账款的比例,发现拖欠原因和解决方法。
